Abstract

PROBLEM TO BE SOLVED: To obtain a conveyer device which can convey flux coated articles by avoiding the peeling down of the flux on the surfaces of the articles as much as possible. SOLUTION: Flux coated articles 6 are conveyed being loaded on a ring belt 5 which consists of plural lines of elastic line members separated from the upper surface of a belt main body 4 of a conveyer belt 1, and are contacted with the conveyer belt 1 only by line-contact with the ring belt 5. As a result, the flux on the surface are attached and transferred to the ring belt 5, being suppressed in a very small amount, and the peeling down of the flux of the flux coating processing articles 6 can be avoided as much as possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conveying a flux-coated product.

[0002]

[0005] Each component such as an aluminum heat exchanger such as an evaporator and a condenser employed in a refrigerant cycle for automobiles is subjected to flux coating on the surface as a pretreatment for brazing. As the flux, for example, as shown in JP-A-4-322896, a viscous liquid flux using a resin material such as polybutene as a dispersion medium is used.

However, when a component having such a viscous flux applied to its surface is conveyed, the flux-coated product comes into contact with another object, so that the flux is peeled off and an appropriate amount of flux cannot be obtained. Would.

Accordingly, the present invention is to provide a flux-applied article conveying apparatus which can convey a flux-applied article while avoiding as much as possible the surface flux from peeling off.

[0005]

According to a first aspect of the present invention, there is provided a conveying apparatus comprising a pair of rotating rollers and a conveying belt suspended over the rotating rollers for conveying a flux-coated product. Wherein the transport belt is constituted by ring belts arranged in rows at appropriate intervals in the width direction.

According to a second aspect of the present invention, the ring belt according to the first aspect is characterized in that the ring belt is mounted so as to be separated from the belt main body surface.

[0007] In the invention of claim 3, claims 1 and 2
A scraper for scraping off the flux adhering to the ring belt is provided below the conveyor belt.

[0008]

According to the first aspect of the present invention, since the flux-coated product is placed and conveyed on the ring belt, it only comes into line contact with the ring belt. Even if it adheres and transfers to the belt, it can be suppressed to a very small extent, so that the flux can be prevented from peeling off as much as possible.

Also, since the amount of flux adhering to the conveyor belt can be suppressed to a small extent, it is not necessary to increase the amount of flux applied in anticipation of the adhesion of the flux to the conveyor belt, and it is possible to suppress wasteful consumption of flux. In addition, the degree of contamination of the conveyor belt and peripheral equipment can be reduced, and the cleaning operation can be facilitated.

According to the second aspect of the present invention, since the strength of the belt body can be increased, the diameter of the ring belt can be reduced.

According to the third aspect of the present invention, in addition to the effects of the first and second aspects of the present invention, when the transport belt rotates and reverses downward, the flux attached to the ring belt is scraped off. Thus, the conveyance belt can be further prevented from being soiled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a transport belt which is suspended over a pair of rotary rollers 2 and 3 and transports a flux-coated product by rotating the rotary rollers 2 and 3 in the direction of the arrow. .

In this embodiment, the flux-coated product 6 is a corrugated outer fin constituting a core such as an evaporator or a condenser used in an automobile refrigeration cycle.

The outer fin 6 is made of an aluminum material such as aluminum or an aluminum alloy, or a clad material obtained by surface-treating a brazing material layer made of a similar metal on the aluminum material. A flux 9 (see FIG. 2) is applied to enable brazing to a refrigerant tube, a tank or the like (not shown) to which the fin 6 is bonded.

As the flux 9, for example, as described above, a viscous liquid using a resin material such as polybutene as a dispersion medium is used. After the outer fin 6 is coated by a flux coating line (not shown), It is sent onto the conveyor belt 1.

The conveyor belt 1 is formed of an elastic material such as oil-resistant rubber, synthetic resin, or the like, and is formed of a belt body 4 suspended over the rotating rollers 2 and 3, and formed of the same material as the belt body 4. A ring belt 5 made of a plurality of elastic filaments which are arranged in rows on the surface of the belt main body 4 at appropriate intervals in the width direction and on which the outer fins 6 are placed apart from the surface of the belt main body 4. It consists of:

The ring belt 5 may have a diameter such that the mounted outer fins 6 have such a protruding height that the outer fins 6 do not touch the surface of the belt body 4, and are bonded or fused to the surface of the belt body 4. And are integrally formed.

The lower end of the conveyor belt 1 is elastically in contact with the ring belt 5 so that the ring belt 5
A scraper 7 for scraping off the flux 9 adhered to the container 8 and collecting it in the container 8 is provided.

According to the structure of the above-described embodiment, the outer fins 6 subjected to the flux application processing are mounted on the ring belt 5 made of a plurality of elastic filaments while being separated from the surface of the belt body 4 of the transport belt 1. Is placed and conveyed, and only makes line contact with the ring belt 5 with the conveyor belt 1,
Even if the flux 9 on the surface adheres and transfers to the ring belt 5, the flux 9 can be suppressed very slightly, and therefore, the flux 9 can be prevented from peeling off from the outer fin 6 as much as possible.

Further, as described above, the amount of flux adhering to the conveyor belt 1 can be suppressed to a small amount, so that it is not necessary to increase the amount of flux applied to the outer fins 6 in anticipation of the adhering of the flux 9 to the conveyor belt 1. In addition, wasteful consumption of the flux 9 can be suppressed, and the degree of contamination of the transport belt 1 and peripheral equipment can be reduced, thereby facilitating the cleaning operation.

Further, according to the present embodiment, when the transport belt 1 rotates and turns downward, the flux 9 attached to the ring belt 5 is scraped off by the scraper 7 as shown in FIG. Therefore, the prevention of contamination of the conveyor belt 1 can be further improved.

Although the ring belt has been described as having a circular cross section, it may have a semicircular cross section, a triangular cross section, or a rectangular cross section if the width is small.
